Hi
We have built "h8300-elf" toolchain based on gcc-4.1 (released). This
toolchain is based on following sources,
Binutils-2.16.92
Gcc-4.1-20060407
Newlib-1.14.0
Also we have built, GDB for "h8300-elf" using gdb-6.4.50.20060425
We have found following problems for all varients of h8 target,
1. "printf" is not working with this toolchain for simulator.
2. Local variables can not be watched using GDB.
Following is the test case used for testing,
----------------------------------------------------------------
int a = 100;
int main ()
{
printf ("\n H8300-ELF toolchain test. Var = %d\n",a);
return 0;
}
----------------------------------------------------------------
Commands are as follow;
#h8300-elf-gcc -ms -g foo.c
#h8300-elf-run a.out
--> This outputs nothing.
We have also tried following combination,
Binutils-2.16.92
Gcc-4.1.0 (released)
Newlib-1.14.0
However, results are same.
Any help on this will be highly appreciated.
Thanks and regards,
